- 4 Claims. (Cl. 2s 1s1 This invention relates to certain new and usefulimprovements in devices or clamp accessories for use in the formsrequired for the making of concrete building walls and the like.. 1 v

It has for one of itsobjects to provide a concrete form device of thischaracter which is not only simple and inexpensive in construction butwhich facilitates the ready assemblage and retention of the concreteform in a firm and true-position and'which does not damage the woodelements employed upon'removal or disassembling of the form after theWall has set;

Another objectof the invention is to provide a novel self-containedclampassembly for effectually supporting and retaining the customary waleelements of the form assembly against the wall studs.

Other features of the invention reside in the construction andarrangement of parts hereinafter described and particularly pointed outin the appended claims.

vIn the substantial types of concrete building and like wallconstruction, to which our invention is directed, form boards orsheathing are disposed in lateral spaced relation for the pouring of theconcrete wall 11 therebetween and these form boards are secured tovertical studs 12 disposed in spaced relation lengthwise of the form.Disposed edgewise against studs are horizontal boards or wales 13, whichwe dispose in pairs in spaced parallel relation with the joints thereofpreferably in broken or staggered relation. It is our purpose to soconnect these form elements in a firm, even and true manner withoutresorting to nails and like fasteners for so doing and avoid injury ordamage to the lumber when removing the form assembly from the concretewall.

For the purpose of supporting the lower wale 13 of a pair at suitablyspaced points in proper relation to the studs 12, brackets 14 areprovided, each bracket being shaped from metal and detachably secured tothe side face of an adjoining stud through the medium of a nail or likefastener 15 engaging a keyhole-shaped slot 16 in the bracket-wall, therear edge of the bracket abutting the opposing outer face of the formboards 10. Extending laterally from each bracket at right angles theretois a flange 17 which is adapted to overlie the front edge of theadjoining stud to not only square the bracket in position but, jointlywith the fastener 15, properly retain the bracket against displacement.By this construction,

2,902,744 Patented Sept. 8, 1959 these brackets may be applied to andremoved from the studs in a minimum of time and with a minimum ofeffort. These brackets may be of a supporting length to receive two setsof wales in side by side relation where the construction of the wall maywarrant it.

In order to maintain the form boards 10 in their proper position andretain the wales in detachable clamped relation against the studs, weprovide a plurality of tie rods 18 which transversely span the completeform assembly and companion end clamps 19 correlated therewith and withthe wales. These clamps are so constructed that they provide superposedretaining supports for the pairs of parallel wales, they being the solesupport for the upper wales of each pair while the lower wales aresupported as well on the brackets 14. By preference, each of theseclamps is substantially S-shaped in elevation to provideinwardly-opening upper and lower horizontal recesses 20 in which thecompanion wales are received and supported in spaced relation with theclosed front ends 21 of such recesses constituting abutment walls whichbear snugly against the outer edges of the wales to effectually alignand retain them against the studs. The web portion 22 at the inner endof the intermediate or outwardly-opening recess of the clamp between itswalereceiving recesses has a horizontal opening 23 therein through whichthe companion tie rod 18 extends. Applied to the front face of the clampare upright guidefianges 24 in which a vertically-displaceable clampingbar 25 is guided for correlation with thehead of the companion tie bolt18 to draw the form assembly together and resist its expansion duringthe pouring of the concrete into the same. For this purpose this bar hasa downwardly tapering wedge-shaped facial portion 26 having an uprighttie rod receiving slot 27 centrally thereof terminating at its lower endin an enlargement or escapev opening for registration with the tie rodhead in the raised or released portion of the wedge-like clamping i thisbar relative to the clamp and whereby the same forms a unitary orself-contained part of the clamp and is always tied thereto ready foruse.

In assembling the wales tothe sheathing-studs 12, the brackets 14 aredetachably applied to the nails15 of the companion studs 12 on whichsuch brackets are to be mounted, after which the-tie rods 18 arepositioned where desired and the S-shaped clamps 19 with their captiveclamping bars 25 are engaged with the ends of said rods and the wales 13placed insupported relation thereto and to the brackets. The clampingbars are then forced down against the headed ends of the tie rods todraw the wales snugly against the studs and retain the form assemblyfirmly in its aligned position to receive the concrete. Removal of thewales is as readily efiected by releasing the clamping bars from theirwedged position and removing the clamps from such wales, and thebrackets 14 are detached from their stud-nails. In this connection thelumber elements are not injured or wasted in any way and can be used forassembling another form.

It will be noted in Figure 5 that the wedge-face 26 of the clamping bar25 is recessed or counter sunk and that its outer or front face issubstantially straight or upright and serves as an abutment face for theso-called buttons attached to the ends of wire type tie members employedin heavier concrete structures in lieu of tie bolts.
